Believe it or not, I was in the process of updating this post with your first link as I realized I had a comment pending moderation. (I saw the signs for voteformmp.ca on this morning's commute.)

First, to quote your post, you got me: I have yet to read the Ontario Citizens' Assembly's report, but plan to do so shortly.

Second, I know a heck of lot more about this now - including the 3% threshold that mitigates Warren's "fringe" fears, as you say - thanks to The Agenda with Steve Paikin. I've included links to his show in my shared items to the left.

Third, thanks for pointing me to the second link: a withering critique to be sure.
